Mathieulh has updated PSGroove — the open source PS JailBreak implementation. The update won’t serve the average user any real purpose; it’s more for developers. That said, PSGroove payload now includes lv2 peek and poke syscalls. Remember geohot’s work? Yeah. That’s right.

 

This branch has a modified payload that adds peek and poke syscalls to the lv2 kernel. A userspace application can use these syscalls to dump out the entire memory space of the kernel, or patch the kernel as it is running.

Unfortunately, because the free toolchain/sdk is not ready, we can’t distribute an application to do the dumping, so you will have to make your own.

I’ve compiled the PS Groove update — with backup support and without — for Teensy++ boards.
